This invention relates to a machinel for loadingcoal and other material and is especially adapted for loading n'iaterial in mines.

The object of the invention is to provide av machine of the class named which shall be of improved construction V`and operation.

rl`he invention is exemplified in the combination and arrangement of parts shown in 1;, the accompanying drawings and' described in the following specification, and it is more. particularly pointed out in the appended claims. y

Fig. 16 is a diagrannnatic view showing 4a horizontal section through a mine chamber with the machine in operative position.

In some regions mining operations are carried on by first driving a series of parallel entries away from the-mine opening for a considerable distance leaving a series ot ribs betweenthe entries to support the mine roof. After the entries have been driven to the desired distance.V the ribs are cut through at the outer ends of the entries and the coal in the ribs is then removed by working backmachine wardly toward the mouth of the. mine. The final result ot' this method of operation is the removal of all of the coal from the mine vein, leaving the roof to settle in the rear of the operating position during the backward working byv which the ribsare removed. In Fig. 16, the machine, constituting on'e embodiment of the present invention, is shown in position for performing the return operation in the method of mining lreferred to by which the ribs are removed. Although the machine isin no sense limited to this particular operation it is especially well 'adapted-for working bacltwardly toward the material Which is being removed Vand toward the body portion of the machine.

The machine as a whole comprises three pivotally connected sections; the rear section designated by the letter A in the drawings is a conveyer section for discharging the material into the car by which it is transported from the mine chamber; the middle section B carries thel greater part ot the operating mechanismfor the machine and also has pivoptally supported thereon the forward or receiving section C. The main or central section B comprises a trame 20 having front and rear uprights 21 and 22 respectively. which are connected at their lower ends b v side bars 23 and at their upper ends by side' bars 24J The uprights 21 and 22 are slotted at 25 and 26 respectively, at their lower ends to t'orm slideways for journal boxes 27 and 28. Springs 29 and 3() are interposed between the journal boxes and the upper ends ot their respective slots toprovide a resilient support Jr'or the trame 20. AFront and rear axles 31 and 32 are journaled in the boxes 2T and 28 respectively and are provided with track wheels A plate 3-1 extends across the bottom ot the frame 2() between the lower edges ot' the side barsl. A motor 35 is sinrported on the plate 34 and is provided with a pinion 36 (Fig. 11) driving agear wheel 37 carried by a shaft 38 journaled in bearings 39 which are carried by standards 40 (Fig. 13) mounted upon the plate 34. The standards 40 also carry a pair of bearings 41 (Fig. 11) in which the inner ends ot' shafts -l-:Z and 43 are journaled. The outer ends of these shafts are Journaled 1n bearings 44 and 45 respectively, which are formed upon the upper edges of the side plates 23. The shaft` 38 is provided at its outer ends with -a pair of pinions 46 and 47 which mesh with at 55 to the plate 34. VThe rod 54, as shown in Fig. 11, is provided at its upperend with a threaded sleeve 56 which engagesthreads 57 on a rod 58 journaled in the side plate-S23. The rod 5 8 is provided With a hand wheel` 59 by which it is rotated to shift the clutch 51'. The rod 52 is similarly connected with a rod 60 journaled in the upper bars 24 and provided with a hand-wheel 61 (Fig. 4). Drums 62 and 63 (Fig. 11) are secured to the outer endsl of thershafts 42 and 43 respcc tively, and are provided with cables 64 and 65 for a purpose to be described.

A conveyer frame 65 is pivotally mounted p upon a rod` 66 extending across the frame of the machine between the upper side plates`24. as shown in Figs. 4-and 8. The conveyer frame, as shown in Fig. 13, includes side plates 67 connected by a bed plate 68 and angle bars 69 which lie adjacent the outer edges of an endless flight conveyer 70 which travels upon the bed plate 68.- Overhanging lianges 71 are connected with the plates 67" of theconveyer frame and overlie the chains of the conveyer 70, The conveyer 70 is driven by a motor 72mounted on a plate 73 supported by the u rights 22. The motor 72 operates a shaft 4 through reduction gearing contained in a casing 7 5' and the shaft 74 is provided with sprocket wheels 75 which mesh with the chains ofthe conveyer' '70. The upper end of the conveyer 70 passes over suitable sprocket wheels on the bar 66 while the lower end passes over similar sprockets on a shaft 76 at the forward end ofthe conveyer frame 65', as shown in Fig 5 ot' the draw ings. t its fprwardend. the conveyer frame 65 is curved' outwardly to form a hopper' 7 7, as shown in Figs. 5 and 9, and this hopper is provided with a downwardly projecting circular rim,7 8 which carries a flange 7 9 at its lower edge and which is surrounded by a circular band`l80 by means of which the forward section C..0f the machine yis pivotally supported upon the conveyer frame 65. The band 80 carries a pair of bracket plates 81 to the inner surfaces of which are secured the side. plates 82 of the conveyer frame which constitutes the main` portion of the section C of the machine. The plates 82, as shown in Fig. 6, are connected by upper and lower bed plates 83 and 84 and a supplemental plate 85 upon which the return run of the and imparts movement thereto. Hinged to the outer faces of the. horizontal portions of the side plates 82, at their upper edges, is` a pair of swinging platforms 92 and 93,

shown in Figs.`5, 6 and 9: The platform'92 1s shown in its lowered position in Figs.' 6

and.9 while the platform 93 is shown in its raised position, Detents 94 are provided for holding'` the platforms up when they are raised. In'the rear of the plates which form the platforms 92 an 93, and in position to form extensions o these platforms, when lowered, is a lpair of fixed inclined plates 95 and 96 which have their rear ends curved upwardly to form guard plates as shown at 97. It will be seen from Fig. 6 that the plate 93 in its uppermost position forms an upf wardlya-nd uutwardly inclined sideboard for the conveyer 85.; Removable plates 98 are provided to bridge the space between the ends of the plates 92 and 93 and the inclined walls 99 of the conveyer frame adjacent the bracket plates 81. The plates 98 are provided with pins 100 arranged to enter openings 101 to hold the removable side plates 98 in place. One of these plates is shown in place .in Fig. 6 of the drawings. The plate for the opposite side will be similar to the one shown but will be reversedin contour to correspond to itsposition. The forward end. of the conveyer frame is .provided with a forwardly and downwardly inclined platform or nose piece 102 which is shaped at its v outer ends as shown at 103 to form a continuation of the hinged platforms 92 and 93 when the are in their lowered position. The brac et plates -81 are. provided with guide pulleys 104 and 105 for the cables 64 and 65 and a pair of eyes 106 and 107 are secured to thenose piece 102 at opposite sides of theveonveyer for interchangeably receiving a. guide pulley 108. It will be apparent Y from Figs. 9 and 16 that the receiving section C of the machine may be swung laterally by means of the cables 64 `and 65, the direction of movement depending upon the particular cable used and the way in which it is arranged through the guide pulleys. To swing the receiving section in a clockwise direction, as viewed in Fig. 16, the cable 65 is employed andthe guide pulley 108 is attached to the eye 107 and the cable passed through the pulley and attached to a fi'xed anchor on'the side of themachine toward whlch it is desired ltomove .the conveyer. When the cable is then wound upon its drum, 1t 1s apparent that the receiving section of ooi lIU

modera the machine will be swung in the desired direction. By a similar arrangement of the other cable, a reverse rotation of the section C may be accomplished. As shown in Figs. 14 and 151the supporting ring 80 for the conveyer sect-ion C may be provided with .lugs

110 arranged to contact. with a stop 111 extending downwardly from the under surface of the conveyer section This arrangement limits the angular movement of the receiving section.

In view of the foregoing description of the apparatus embodied in applicants structure as shown in the drawings, it will be evident that the supporting framework constitutes a portable base unit upon which is mounted a conveyer pan C including a depressed forward end or nose portion having a back and forth sweep movement across the floor of the mine, as illustrated in Fig. 16. Upon the marginal edges of the nose portion there are mounted downwardly and outwardly inclined surfaces, as shown at 92 and 93 in Fig. 6, it being understood that both of the marginal edge scoops 92 and 93 may be in their floor contacting positions when desired. It should also be understood that the downwardly and outwardly inclined surfaces 92 and 93 have the inherent function of mains taining the nose portion beneath the material to be loaded and in engagement with the mine floor, thereby preventing the front or nose end of the machine from climbing the coal pile instead of forcing its wayn underneath it. By maintaining the bottom 84 of the nose portion of the conveyer pan on the iloor surface the ring will alsoA be maintained in proper position to permit free rotation of the pan C with its rear end continuously in delivery communication with the hopper 77 throughout an angular movement of over 180.

Mechanism is provided for raising and Y lowering the conveyer section 65 and the receiving portion C of the machine pivotally carried b v the forward end of this conveyer Section. This mechanismiis illustrated in 4 and 11 and comprises a sleeve 112 loosely mounted on the axle 31 and carrying an arm 113 to which a link 114 is pivotally connected. The link 114 has its upper end pivoted to a lug 115 extending downwardly from the under surface of the conveyer section 65. The sleeve 112 and arm 113 are resiliently held in position -to support the conveyer section 65 by a counterbalancin spring 116 having one end attached to the plate 34 and the other end attached to an arm 117 secured Yto the sleeve 112. 'Another arm 118 is carried by the sleeve`112 and has a. link 119 pivotally connected to the outer end thereof. The oppositeend of the link 119 is pivoted to an arm 120 rigidly connected to a shaft 121 journaled in the side plates 23 of the machine frame. The shaft 121 carries parent that-the arm 113 will be rocked upi wardly to raise the conveyer section 65 and the mechanism supported thereon above the surface of the mine floor and into position Vto permit transportation of the machine along the support' track.

The rear or disc arge section A of the machine includes a hopper 125 which is pivotally supported at 126 on a rearwardly extending bracket 127 carried by the frame 20 of the central section B. An upper bracket 128 is pivot-ally connected at 129 to a bar 130 secured to the upper portion of the hopper 125. This pivotal connection permits relative movement between the sections A and B to allow the machine to pass around sharp curves in the track over which it is transported. It is apparent that the conveyer 70 will discharge into the hopper 125 irrespective of the relative angular position of the J1 two sections of the machine. The hopper 125 is continued rearwardly to form a conveyer frame 131 over which an endless flight conveyer 132 travels. The hopper and conveyer are supported by a truck frame comprising uprights 133 and 134 which are connected together at their lower ends by bars 135. The bars 135 are in turn connected by a eros plate 136, as shown in Fig. 10. The uprights 133 and 134 are provided with slideways 137 for journal boxes 138 which form bearings for the axles 139 of the truck. The axles 139 are provided with track wheels 140 which run upon the track 141 over which the machine travels. A motor 142 is otally supported at one side by straps 143 extending around the axle 139 and is rcsiliently supported at its opposite side by springs 144 surrounding an upright rod 145 pivcarried by the cross plate 136. The vmotor 3"" 142 is arranged to rotate the axle 139 through gearing 146. The axles 139 are connected for rotation in unison with one another b v a sprocket chain 147 and sprocket wheels 148. Brake-shoes 150 are arranged to bear upon the wheels and are operated through suitable link mechanism by a lever 151 connected with a cross rod 152 and held in place b v a toothed bar 153.l By this brake mechanism the machine may be secured for moveg ment along the track during the operation of the material handling mechanism The conveyer 132 is driven by a motor 154 which operates sprocket wheels 1.55 connected with the motor through gearing 156. The

motor is supported between the uprights 133 by means of angle bars 157 extending transversely from one of the nprights to the other. The motor 154 is governed by a controller 158 secured to the conveyer frame 131 near the discharge end thereof so that the operation of the conveyer may be re ated by an operator in the car 159 into w 'ch the material is discharged from the loading machine, and by means of which it is transported out ofthemine chamber.v The various other -motors for operating the different parts of the machine are governed by a series of controllers 160 carried by the upper side plate 24 of the central section B.

In 'operating the machine to. load coal that has been broken down at the outer ends of a pair of ribs in a mine chamber, as illustrated in Fig. 16, themachine is moved along the track to bring the `receiving section C into a position adjacent the ends of the ribs being worked. In breakin the coal down portions of it will probably fa into the ntry in which the machine is operated and is will be re- L moved first by forcing the nose piece 102 beneath the Vmaterial in front of the machine. This may be done either by driving the ma'- chine forwardly by theV rotation of its track wheels, or by anchoring the cables 64 and 65 to fixed supports in front of the machine and then winding the cables upon their respective drums. During this operation the endless conveyers will, of course, be driven to carry the coal to the rear of the machine and 'discharge it into the car 159. After a passage has Athus been opened of suiicient width to receive the receiving section C of the machine, the machine will be located, as shown in lines in Fig. 16. The cable 65 may then be trained through theA guide pulleys 105 and 108 and attached to an anchor, as shown at 165 in Fig. 16. The plate 92 is arranged in its lowered position while the lplate 93- is swung upwardly and the remova le plate 98 is placed in position to cooperate with the l plate 93 to form a wall along the side of the i conveyer opposite the receiving side 92. The

cable 65 may now be wound upon its drum and the receiving section C of the conveyer will be swung in a clockwise direction, as viewed in Fig. 16, and the side of the conveyer section C will be forced beneath the loosened coal along substantially its entire length.v As the receiving section 1s moved beneath the coal, the'endless conveyer 86 will carry the coal rearwardly and upwardly and discharge it upon .the conveyer of the central section BA from .whence it will be carried backwardly and loaded into the cars for transportation. As the loading operation pro and the section C is swung farther about its pivotal support, the anchor for the cable 65 may be shifted, as indicated -in broken lines in Fig. 16. When the receiving lsection C finally reaches a position at right angles to the'main body of the machine, one of the lugs 110 will strike the stop 111 and prevent further rotary movement of the conveyer section. The operation will be continued, however, by fur-v ther the cable 65 which will move thc entire machine along the track in a rearward direction and carry thewonveyer section C backwardly with its receiving side at right angles to the direction of movementof the machine. Therefore as each successive rtion of the ends of the pillars shown in ig. 16 'are dislodgedby blasting or otherwise the receiving conveyer section C may be swung from an inclined position alon'g horizontal lines toa right angle 'tion as determined by the limit stop mt'eclllimliism shown in Figs. 14 and' 15. When the outer end of the rope is anchored and the limit stop mechanism prevents further swinging movement of the conveyer section C continued ull on the rope while the brake mechanism s own in Fig. 3 is released will caus the'whole machine to move along the mine track and 'thuseect rectilinear movement of the receiver of the conveyer section C in--a direction parallel to themine track and along lines extending transversely of said receiver. The material scooped up by the digger' 92 or 93 will be directed onto' the endless conveyer of the recei'ver which conveyeris in central position and compact by reason of being composed of superposed portions adapted to .travel in opposite directions. During this portion of the operation the brakes u n Vvthe track wheels will be released to permit the rearward movement of the machine. If desired the cable 164 may be employed to aid in the rearward movement of the machine, the arrangement of the cable for this purpose being indicated in Fig. 16. As shown inthat view, the cable passes around its guide pulley 104 and is secured to an anchor 166 in the entry and in the rear of the pulley 104.. After the loosened material on .one side of the entry has all been collected, the operation is'reversed and the receiving section C swung Vin the opposite direction to load .the-coal on the other side of the entry.. In this way two adjacent ribs of the mine may be removed by operating from asingle entry between the two.

The forward conveyor section C is adapted to rest on and slide over the mine loor as shown in Figs. 2 and 5. On account of the 'bottom 84 of the frame 82 being flat the conveyor section is moved along horizontal arcuate lines when swung about the hopper 77. An endlcis conveyor on the section C has superposed portions traveling in opposite directions as illustrated in dotted lines in Fig. 5. Such direction of travel is transversely of such horizontal lines. The upper receiving portion of the conveyor is in a horizontal plane as shown in Fig. 5. Extending along the lateral faces of the frame of the conveyor section C over the greater length thereof are scoops 92 and 93 (Figs. 1, 2 and 6) for directing material from the mine Hoor onto the upper horizontal receiving portion of the l conveyor. By providing endlessA conveyor ment in loading machines, there is described and a structure Vfor effecting loading of material from a mine lloor in advance of a mine track by longitudinal movement -of a whole machine along the mine track and by swinging movement lateraly relatively to the mille track, but in vsuch constructmn the scooping plane extends across the outer end` of the gathering device and this gathering device must be moved into positions extending laterally from the forward end of the machine before late-ral swinging movements are effected. The width of thescoop is limited by the width of the gathering device b ecause the. machine'must travel along narrow entries, and thereforewthe capacity' of loading b v lateral swinging movementsis limited. The structure shown in the present application is an improvement on that disclosed in `Serial No. 185.118 in that the scooping means extends not only across the outer endd of the gathering device, but also along both sides of the gathering device which' is elongated as shown in Figs. 1 and 2. Consequently the relatively narrow scoop 102 may be used in a narrow entry when rfirst beginning loading operations and the elongated lateral scoops 9; and 93 are effective in eiciently performing the operations illustrated in Fig. 16 for gathering and loading the material dislodged from the ends of the coal pillars as hel-einbet'ore fully described.-

Furthermore, in Serial No. 186,118 there is shown only two conveyers, while in the present application the conveyor apparatus is divided into three sections as shown at A, B and C in Figs. 1 and 2, the intermediate scciion being mounted on the forward truck f rame while being confined against lateral movement but holdingthe forward hopper '('7 central of the mine track while the gathering device C may'perform the operations illustrated in Fig. 16. In Serial No. 186,118 there is also described and shown mechanism for elevating the gathering device for transpor-` tation. butsuch elevating mechanism is lmwei-oyx-.ratmh In the. present application as shown in Fig. fl, the lever 122 is connected to the section' l so that the lat-ter together with the gathering Ydevice. C may be elevated above the plane of the. track for transportation purlmses. This operation may easily be etected by means of the lever 122 by reason of the presence of the counter-balancing mechanism shown at 116 in Figs. 4 and 11. lVhen electric power is not available and it is desiredto elevate the gathering device C for i transportation by means of an electric lococxtend through 180 motive coupled tothe loading machine shown, the hand-operated inc iehani'sm may be relied on. Furthermore,tl1e rope gearing arranged as shown in the present application is an imvprovement over the swinging rope gearing in Serial N o. 186,118 in that in the latter the swinging movement is comparatively limited, whereas in the present application the swinging movements of the y as illustrated in 16.

Obviously those skilled in the art may make various changes in the construction and arrangement of'parts without departing from the spirit and scope of the. invention kas defined by the claims hereto appended" and therefore it is to'be understood that the invention is not to be restricted to the n precise constructlon herein disclosed:
